Answer 1

Ok, I found one hack ( which i knew exists ) ,which i was not looking for but it worked and solved my problem in a very simple way.

You can run shell commands in mk file.

So if you want to copy multiple files just in a single go use following code and place it in your mk file.

In following scenario the files i need to copy are present in file_folder ( directory ) , which is in same directory where my mk file is. And i wan to copy all the files present in file_folder to system/file_folder.

#create a directory in /system/
    $(shell mkdir -p $(TARGET_OUT)/file_folder/)
#copy stuff
    $(shell cp $(LOCAL_PATH)/file_folder/* `pwd`/$(TARGET_OUT)/file_folder/)

This worked fine. So now in all we have 3 ways to do it. Hope it will help someone like me.

Answer 2

See the following example in Android font handling: https://android.googlesource.com/platform/frameworks/base/+/master/data/fonts/Android.mk#66

This creates a makefile function for a single font file, and uses a foreach loop to iterate over multiple files: https://android.googlesource.com/platform/frameworks/base/+/master/data/fonts/Android.mk#79

You can use any mechanism to populate font_src_files
